[0001] This invention relates to the field of air handling equipment technology, and more specifically to air handling methods, air handling equipment, and computer-readable storage media. Background Technology

[0002] Air purifiers and other air handling equipment can purify indoor VOCs, odors, bacteria, and microorganisms. Glow discharge (including glow plasma, corona discharge, etc.) deodorization technology, with its advantages of thorough decomposition, no adsorption saturation problem, and dual effects of sterilization and deodorization, is often used in mid-to-high-end air purifiers.

[0003] However, the glow discharge deodorization technology ionizes oxygen in the air to generate ozone during the discharge process. Ozone is an irritating and harmful gas. Excessive ozone can easily irritate the human respiratory tract and damage mucous membranes. Long-term exposure to excessive ozone can harm the user's health. Summary of the Invention

The deodorization module of the air handling equipment is controlled to perform graded intelligent discharge based on the optimal discharge parameters.

[0006] Beneficial effects: Based on real-time acquisition of multi-dimensional air-related data, the target deodorization efficiency and the allowable upper limit of ozone generation are obtained. Then, based on the target deodorization efficiency, the allowable upper limit of ozone generation, and a preset prediction model, the optimal discharge parameters of the air handling equipment are obtained. The deodorization module of the air handling equipment is then controlled to perform graded intelligent discharge according to the optimal discharge parameters. This achieves precise source control of ozone in the early stages and intelligent management of dynamic adaptation to mid-term operating conditions. During the discharge process of the deodorization module, the ozone generated by ionization is intelligently controlled. While ensuring the purification effect of VOCs (volatile organic compounds) and odors, the ozone release is stably controlled within an appropriate range, reducing the safety hazards of ozone leakage due to excessive ozone, reducing the irritation to the human respiratory tract and damage to mucous membranes caused by excessive ozone, improving the health performance of the air handling equipment, extending the service life of the deodorization module and the ozone reduction network of the air handling equipment, and improving the safety and user experience of the air handling equipment.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, in one aspect, an air treatment method is provided, comprising: S1. Real-time acquisition of multi-dimensional air-related data.

[0043] S2. Obtain the target deodorization efficiency and the allowable upper limit of ozone generation based on the multi-dimensional air-related data.

[0044] S3. Based on the target deodorization efficiency, the allowable upper limit of ozone generation, and the preset prediction model, obtain the optimal discharge parameters of the air handling equipment.

[0045] S4. Control the deodorization module of the air handling equipment to perform graded intelligent discharge according to the optimal discharge parameters.

[0046] Based on real-time multi-dimensional air-related data, the target deodorization efficiency and the permissible upper limit of ozone generation are obtained. Then, based on the target deodorization efficiency, the permissible upper limit of ozone generation, and a preset prediction model, the optimal discharge parameters of the air handling equipment are obtained. The deodorization module of the air handling equipment is then controlled to perform graded intelligent discharge according to the optimal discharge parameters. This achieves precise source control of ozone in the early stages and intelligent management of dynamic adaptation to mid-term operating conditions. During the discharge process of the deodorization module, the ozone generated by ionization is intelligently controlled. While ensuring the purification effect of VOCs (volatile organic compounds) and odors, the ozone release is stably controlled within an appropriate range, reducing the safety hazards of ozone leakage, reducing the irritation to the human respiratory tract and damage to mucous membranes caused by excessive ozone, improving the health performance of the air handling equipment, extending the service life of the deodorization module and the ozone reduction network of the air handling equipment, and improving the safety and user experience of the air handling equipment.

[0047] In a specific implementation, the odor removal module is a glow discharge module.

[0048] In one embodiment, the preset prediction model includes an adaptive nonlinear prediction model; obtaining the optimal discharge parameters of the air handling equipment based on the target deodorization efficiency, the allowable upper limit of ozone generation, and the preset prediction model includes: S21. Based on the target deodorization efficiency, the allowable upper limit of ozone generation, and the adaptive nonlinear prediction model, obtain the optimal discharge power of the air handling equipment, and obtain the discharge voltage, discharge frequency, and duty cycle that the drive circuit can execute according to the optimal discharge power.

[0049] Based on the target deodorization efficiency, the allowable upper limit of ozone generation, and the adaptive nonlinear prediction model, the optimal discharge power of the air handling equipment is obtained. Then, the discharge voltage, discharge frequency, and duty cycle that the drive circuit can execute can be obtained according to the optimal discharge power. The nonlinear influence of the discharge parameters of the deodorization module, environmental conditions, and device aging degree on ozone generation and deodorization effect can be accurately captured, so as to achieve more precise control of the deodorization module of the air handling equipment.

[0050] In one embodiment, controlling the deodorization module of the air handling device to perform graded intelligent discharge according to the optimal discharge parameters includes: S41. Perform safety threshold verification based on the optimal discharge parameters, deodorization requirements, ozone prediction, and measured safety threshold.

[0051] S42. If the verification passes, the air handling equipment is controlled to perform graded intelligent discharge according to the optimal discharge parameters based on the pollution level.

[0052] S43. If the verification fails, take safety measures to intervene in the air handling equipment.

[0053] A safety threshold verification is performed based on the optimal discharge parameters, odor removal requirements, ozone prediction, and measured safety threshold, implementing a triple judgment mechanism to avoid safety risks caused by misjudgment of a single parameter. Furthermore, after successful verification, the air handling equipment is controlled to perform graded intelligent discharge according to the pollution level and optimal discharge parameters, enabling more precise control of the air handling equipment. If the verification fails, safety intervention is implemented on the air handling equipment, improving control accuracy in subsequent control processes and obtaining more precise data while maintaining safety.

[0054] In one embodiment, the preset prediction model includes an ozone generation prediction model and an odor removal efficiency prediction model; the safety threshold verification based on the optimal discharge parameters, odor removal requirements, ozone prediction value, and measured safety threshold includes: S411. Based on the ozone generation prediction model, obtain the estimated ozone generation for a single period, and obtain the comparison result between the estimated ozone generation for a single period and the upper limit of ozone generation.

[0055] S412. Based on the deodorization efficiency prediction model, obtain the estimated deodorization efficiency and obtain the comparison result between the estimated deodorization efficiency and the target deodorization efficiency.

[0056] S413. If the estimated ozone generation in a single cycle is less than or equal to the upper limit of ozone generation, and the estimated deodorization efficiency is greater than or equal to the target deodorization efficiency, the verification is passed. Then, according to the pollution level, the air handling equipment is controlled to perform graded intelligent discharge based on the optimal discharge parameters.

[0057] Based on the ozone generation prediction model, the estimated ozone generation for a single period is obtained, and then the estimated ozone generation for a single period is verified against the upper limit of ozone generation. Based on the deodorization efficiency prediction model, the estimated deodorization efficiency is obtained, and then the estimated deodorization efficiency is verified against the target deodorization efficiency. Based on the above dual constraints, through traversal solution and gradient optimization, the optimal discharge power that meets the deodorization requirements and has the lowest ozone generation is obtained, and then converted into control commands such as discharge voltage, discharge frequency and duty cycle that can be executed by the drive circuit.

[0058] In one specific implementation, the ozone generation prediction model is as follows: .

[0059] Among them, O 3,pre The values ​​are: α0 - Single-cycle estimated ozone generation (mg / h); P - Discharge power of the deodorization module (P=U×I, W); α0 - Intercept term (factory calibration); α1 - Linear power coefficient (linear increase in ozone generation with power); α2 - Nonlinear correction coefficient (capturing the nonlinear variation characteristics of ozone generation under high power, factory calibration); α3 - Humidity correction coefficient (ozone generation during glow discharge changes under high humidity, based on experimental calibration); α4 - Aging correction coefficient (module aging and ozone generation characteristic drift due to cumulative operating time, supports online updates); α5 - Airflow correction coefficient (airflow affects gas residence time and ozone carry-out in the discharge area, factory calibration); α6 - Humidity correction coefficient (ozone generation during glow discharge changes under different temperature conditions, based on experimental calibration).

[0060] In one specific implementation, the odor removal efficiency prediction model is as follows: .

[0061] Where, η voc,preTo estimate the deodorization efficiency; γ0, γ1, and γ2 are factory-calibrated coefficients, capturing the marginal decrease in deodorization efficiency with decreasing discharge power and saturation characteristics; k voc This is a pollutant concentration correction factor, based on dynamic adjustment of the TVOC concentration at the air inlet; k RH k H This is a temperature and humidity correction factor, which is adapted in real time based on environmental parameters.

[0062] In one embodiment, the safety threshold verification based on the optimal discharge parameters, deodorization requirements, ozone prediction, and measured safety threshold further includes: S414. Real-time acquisition of ozone concentration at the air outlet of the air handling unit.

[0063] S415. If the ozone concentration at the air outlet exceeds the warning threshold, the verification fails, and the air handling equipment is controlled to adjust the discharge power downward.

[0064] S416. If the ozone concentration at the air outlet exceeds the national standard limit, the verification fails, and the air handling equipment is shut down.

[0065] The ozone concentration at the air outlet directly reflects whether ozone is excessive. By comparing the ozone concentration at the air outlet with the warning threshold and the national standard limit, the air handling equipment can be controlled accordingly to ensure the air purification effect while keeping the ozone release within an appropriate range.

[0066] In one embodiment, the safety threshold verification based on the optimal discharge parameters, deodorization requirements, ozone prediction, and measured safety threshold further includes: S417. Real-time acquisition of the measured deodorization efficiency and ozone concentration at the air outlet of the air handling equipment; S418. If the measured deodorization efficiency is lower than the first preset percentage of the target deodorization efficiency, the verification fails. Under the premise that the ozone concentration at the air outlet is less than or equal to the upper limit of ozone generation, the discharge power is adjusted.

[0067] The measured odor removal efficiency reflects the odor removal effect of the odor removal module. By verifying the measured odor removal efficiency and adjusting the discharge power while ensuring that the ozone concentration at the air outlet is within a reasonable range, the ozone release can be stably controlled within an appropriate range while maintaining the air purification effect.

[0068] In one specific implementation, the first preset percentage may be 20%.

[0069] In a specific implementation, the safety threshold verification includes main control logic, a first auxiliary verification logic, and a second auxiliary verification logic. The main control logic, based on optimal discharge parameters, determines whether the estimated ozone level is within the allowable upper limit while also meeting the target deodorization efficiency, thereby determining the basic control strategy. The first auxiliary verification logic monitors the real-time ozone concentration at the air outlet. If the ozone concentration at the outlet exceeds the warning threshold (80% of the national standard limit), the discharge power of the deodorization module is reduced; if it exceeds the national standard limit, a shutdown protection procedure is immediately executed. The second auxiliary verification logic verifies the measured deodorization efficiency. If the measured deodorization efficiency is more than 20% lower than the target deodorization efficiency, the discharge power of the deodorization module is finely adjusted within the allowable upper limit of ozone to ensure the purification effect.

[0070] In one embodiment, if the verification passes, controlling the air handling equipment to perform graded intelligent discharge based on optimal discharge parameters according to the pollution level includes: S421. Obtain the TVOC concentration at the air inlet of the air handling unit.

[0071] S422. If the TVOC concentration at the air inlet meets the condition that the TVOC concentration at the air inlet is less than or equal to a first preset value, then the deodorization module of the air handling equipment shall be shut down.

[0072] If the TVOC concentration at the air inlet meets the condition of ≤ first preset value, the pollution level is considered to be in clean standby mode. At this time, the indoor air quality meets the standards, and the deodorization module of the air handling equipment can be turned off, while only environmental monitoring is maintained to avoid ozone generation.

[0073] S423. If the TVOC concentration at the air inlet meets the first preset value < TVOC concentration at the air inlet ≤ second preset value, then control the deodorization module of the air handling equipment to start and stop intermittently according to the optimal discharge parameters.

[0074] If the TVOC concentration at the air inlet meets the first preset value < TVOC concentration at the air inlet ≤ second preset value, then the pollution level is considered to be light pollution. At this time, the deodorization module of the air handling equipment is controlled to start and stop intermittently according to the optimal discharge parameters. That is, after matching the optimal discharge parameters, an intermittent start-stop cycle of "running for t1 minutes and stopping for t2 minutes" is adopted. While ensuring the deodorization effect, the cumulative amount of ozone generation is greatly reduced, and sufficient decomposition time is reserved for the ozone reduction network.

[0075] In a specific implementation, t1 minutes can range from 2 minutes to 5 minutes, and t2 minutes can range from 4 minutes to 8 minutes.

[0076] S424. If the TVOC concentration at the air inlet meets the second preset value < TVOC concentration at the air inlet ≤ third preset value, then the discharge power of the deodorization module of the air handling equipment is dynamically adjusted based on the real-time operating conditions.

[0077] If the TVOC concentration at the air inlet meets the second preset value < TVOC concentration at the air inlet ≤ third preset value, then the pollution level is considered to be moderate pollution. At this time, the discharge power of the deodorization module of the air handling equipment is dynamically adjusted based on the real-time operating conditions, and the ozone generation is always kept within the allowable upper limit in a closed loop, taking into account both deodorization efficiency and ozone safety.

[0078] S425. If the TVOC concentration at the air inlet meets the condition that the TVOC concentration at the air inlet is greater than the third preset value, then the ozone concentration and deodorization efficiency are obtained in real time, and the discharge power of the deodorization module of the air handling equipment is gradually increased within the safe threshold of the ozone concentration and the deodorization efficiency.

[0079] If the TVOC concentration at the air inlet meets the condition that the TVOC concentration at the air inlet is greater than the third preset value, then the pollution level is considered to be moderate pollution. At this time, the progressive power mode is triggered to obtain the ozone concentration and deodorization efficiency in real time, and gradually increase the discharge power of the deodorization module of the air handling equipment within the safe threshold of the ozone concentration and the deodorization efficiency.

[0080] In one specific embodiment, if the verification passes, controlling the air handling equipment to perform graded intelligent discharge according to optimal discharge parameters based on the pollution level includes: S421. Obtain the TVOC concentration at the air inlet of the air handling unit.

[0081] S422. If the TVOC concentration at the air inlet meets the requirement of ≤0.05mg / m³, then the deodorization module of the air handling equipment shall be shut down.

[0082] S423. If the TVOC concentration at the air inlet meets the requirement of 0.05 mg / m³ < TVOC concentration at the air inlet ≤ 0.3 mg / m³, then the deodorization module of the air handling equipment is controlled to start and stop intermittently according to the optimal discharge parameters. After matching the optimal discharge parameters, it operates in an intermittent start-stop cycle of "run for 3 minutes, stop for 5 minutes".

[0083] S424. If the TVOC concentration at the air inlet is 0.3 mg / m³ < TVOC concentration at the air inlet ≤ 1.0 mg / m³, the discharge power of the deodorization module of the air handling equipment is dynamically adjusted based on the real-time operating conditions.

[0084] S425. If the TVOC concentration at the air inlet meets the requirement of >1.0 mg / m³, then the ozone concentration and deodorization efficiency are obtained in real time, and the discharge power of the deodorization module of the air handling equipment is gradually increased within the safe threshold of the ozone concentration and the deodorization efficiency.

[0085] In one embodiment, if the verification passes, controlling the air handling equipment to perform graded intelligent discharge based on optimal discharge parameters according to the pollution level further includes: S426. If the air handling device is in sleep mode or silent exclusive mode, the maximum discharge power of the deodorization module of the air handling device is controlled to be lower than the second preset percentage of the rated power, the deodorization module is controlled to start and stop intermittently, and the safety redundancy coefficient is reduced.

[0086] When the air handling unit is in sleep mode or silent dedicated mode, regardless of the pollution level, it automatically limits the maximum discharge power of the glow module to no more than the second preset percentage of the rated power, prioritizes intermittent operation mode, and lowers the safety redundancy coefficient to further tighten the upper limit of ozone generation, thereby minimizing the risk of ozone release and operating noise.

[0087] In a specific implementation, the second preset percentage can be 30%.

[0088] In one embodiment, the real-time acquisition of multi-dimensional air-related data includes: real-time acquisition of inlet TVOC concentration, inlet PM2.5 concentration, rated airflow of the air handling equipment fan at the corresponding speed, real-time running time, inlet air temperature, inlet air humidity, outlet TVOC concentration, and outlet ozone concentration.

[0089] The inlet TVOC concentration, inlet PM2.5 concentration, rated air volume of the air handling unit's fan at the corresponding speed, real-time running time, inlet air temperature, inlet air humidity, outlet TVOC concentration, and outlet ozone concentration can provide good feedback on multi-dimensional air quality data and relevant data of the air handling unit.

[0090] In one embodiment, the air treatment method further includes: S5. After each complete operating cycle, the air handling equipment obtains the predicted and measured values ​​of the calibration indicators, and calculates the deviation rate based on the predicted and measured values.

[0091] S6. If the deviation rate is less than or equal to the deviation percentage, then record all the data from this run.

[0092] S7. If the deviation rate is greater than the deviation percentage and the measured ozone value is higher than the expected value, the discharge power of the deodorization module of the air treatment equipment is reduced, and the online correction of the model coefficients is triggered.

[0093] After each complete operating cycle, the deviation rate between the predicted and measured values ​​of the calibration indicators is checked, and closed-loop correction is performed based on the measured data to ensure control accuracy.

[0094] In a specific implementation, the deviation percentage can be 10%. A complete running cycle can range from 8 minutes to 12 minutes.

[0102] If the ozone concentration at the air outlet momentarily exceeds the national standard limit, the ozone level is exceeded and emergency measures are required. In this case, the deodorization module of the air handling unit should be shut down immediately, and the fan of the air handling unit should be controlled to run at the highest level for a preset time to purge the residual ozone.

[0105] If the TVOC concentration at the air inlet is greater than the preset concentration, and the duration is greater than or equal to the preset duration, then the high pollution emergency adaptation program will be activated. A high pollution alert will be issued to the user through the display screen of the air handling equipment or through the APP. The alert content may be "A high concentration of VOCs has been detected in the current environment. The equipment will optimize the deodorization mode within a safe range. It is recommended to keep the room ventilated."

[0106] In a specific implementation, the preset concentration can be 5.0 mg / m³, and the preset duration can be 10 minutes.

[0107] In one embodiment, the air handling method further includes: if abnormal data is detected from the sensor at the air inlet, automatically triggering a sensor fault alert and suspending the high-power operation of the deodorization module of the air handling device.

[0108] When sensor data is abnormal (such as the TVOC / ozone concentration at the air outlet being consistently higher than that at the air inlet, or the data remaining stable), a sensor fault alert will be automatically triggered, suspending the high-power operation of the deodorization module of the air handling equipment to avoid control deviations and safety risks caused by erroneous data.

[0109] In one embodiment, the air handling method further includes: if the fan of the air handling equipment stops, the speed and air volume are mismatched, or the air passage is blocked abnormally, then the deodorization module of the air handling equipment is shut down, and a fan failure reminder is pushed out.

[0110] If the fan of the air handling unit stops, the speed and air volume are mismatched, or the air passage is blocked, it is considered that the fan is abnormal. The deodorization module of the air handling unit is then shut down to prevent ozone from accumulating in the equipment cavity, eliminate the risk of high-concentration leakage, and at the same time, a fan failure reminder is sent.

[0111] In a specific implementation method, the target deodorization efficiency is dynamically set based on the TVOC concentration at the air inlet, achieving a precise match between "pollution level" and "purification intensity". target The precise value.

[0114] In a specific implementation, the permissible upper limit for ozone generation is O 3,max The calculation formula is as follows: O 3,max =(C limit ×Q i ) / (1-η decomp ×k age )×k safe .
